Challenge Option market‑makers (i.e., clearinghouse members who serve as counterparties to all contracts) prefer a business model in which they pair off positions. For example, if one trader wants to take a long position in a particular option, the market‑maker would ideally find another trader willing to take the corresponding short position in the same contract. The market‑maker then earns the bid–ask spread, while the two traders bear the underlying risk. In practice, however, demand is often highly correlated: if one trader wants a long position, many others typically want the same long position, and few are willing to take the short side. As a result, market‑makers frequently cannot offset positions and instead must synthetize the options they sell. Due to news of a strategic pivot to artificial intelligence, retail traders are clamoring for shares of the shoe company Allbirds, Inc., betting that the stock price will “pop” after a sudden increase from $4 to its current level of $10. These traders are using options in order to achieve substantial financial leverage. As a result, a market‑maker has received an overwhelming number of buy (long) orders for DOOM 0DTE options, with few or no offsetting sell (short) orders. The market-maker believes that if the price does “pop,” it will finish the day at $30. If the price does not pop, they expect it to fall to $7 by the end of the day. The one‑day gross risk‑free rate is effectively zero (i.e., R = 1.00). Choose the transactions required to synthesize an option with a $20 strike price.  

Three Clades Urodela, Apoda, and Anura are all ________________.

Chainlink: What are the most important ways a Chainlink price feed could fail or be manipulated? Focus on the two or three most realistic scenarios. For each, explain the mechanism by which the failure would occur, who would be affected and how the system is designed to prevent or mitigate it.  Maple: Who ultimately bears risk on Maple, and how is that risk distributed across participants? Explain how the protocol attempts to manage credit risk and where those mechanisms may fail. Focus on the most important sources of risk and how losses would actually be realized.  Aave: Who ultimately bears risk in Aave, and how is that risk managed? Focus on the two or three most important risks (e.g., borrower default, collateral volatility, liquidity risk). For each, explain how the protocol attempts to manage the risk and how losses would actually occur if those mechanisms fail.

Due to geopolitical crises, the stock prices of North American oil drillers have risen significantly. The price of Exxon stock has increased from $100 per share to its current level of $155. Today, retail traders are betting that these stocks will be “crushed” by a surprise resolution to the crises. As a result, a market‑maker has received an overwhelming number of buy (long) orders for DOOM 0DTE options, with few or no offsetting sell (short) orders. The market‑maker believes that if the price is “crushed,” it will finish the day at $115. If it isn’t, it will finish the day at $160. The one‑day gross risk‑free rate is effectively zero (i.e., R = 1.00). Choose the transactions required to synthesize an option with a $135 strike price.
